My sons' desktops, running Windows 7 Home Premium 64-bit, both became unusable around 5 days ago. The only hardware they have in common is their WD 1TB hard-drives, each a year old. When the desktops were allowed to boot normally, they would become unresponsive after around 30 seconds. The mouse cursor would change to the Windows spinning circle and any open application windows would turn white.
When booted into safe-mode, both worked fine. They each had Kaspersky Internet Security 2014 installed. Neither of their restore points could be loaded. When Kaspersky was used to scan them in safe-mode, nothing was found. When MalwareBytes (free version) was executed in safe-mode, a few instances of PUPs were found, Babylon and InstallIQ, but nothing else. When Bitdefender was run from a bootable thumbdrive, nothing was found. Using Clonezilla on a bootable thumbdrive, I imaged their drives using backups I maded 1 year ago (embarrassing) and their computers are functional again.
At one point during the creation and testing of the bootable thumbdrives, I booted my computer with one plugged-in. My computer now has the same symptoms that theirs started with. My machine has no hardware in common with theirs. Its running the same OS, Windows 7 Home Premium 64-bit, and Kaspersky Internet Security 2014. In safe-mode I've run Kaspersky IS 2014, MalwareBytes, rkill, TDSSKiller, and Windows Defender. Using bootable CDs I've run Bitdefender, Kaspersky Rescue 10, bootrec.exe from Windows System Repair, Microsoft Defender Offline and Comodo Rescue. I've found nothing other than the InstallIQ and Babylon PUPs and have removed them. I do not have a disk image that I can use to recover. I'm ready to remove my personal data, wipe my drive, and reinstall Windows, but would rather find a less destructive solution. Also, if this infection reoccurs in a week, I don't want to go through the image restore and reinstall festival again.
Thank you for any help you can provide,
